以通過它的極數(shù)判斷它的額定轉(zhuǎn)速，湖北中型電機報價。那么電機的極數(shù)和轉(zhuǎn)速有什么關(guān)系呢？電機的極數(shù)是指每相線圈在定子圓周內(nèi)均勻分布的磁極數(shù)。磁極都是成對出現(xiàn)，N極和S極，所以一臺電機的極數(shù)<span style="display:none;"></span>**少是2極。級數(shù)越多，轉(zhuǎn)速越低，極數(shù)越少，轉(zhuǎn)速越高。轉(zhuǎn)速和極數(shù)的關(guān)系可通過公式：n=60f/p計算。n：轉(zhuǎn)速。 </p> <p> 60：60秒，我們平時所說的這臺電機的轉(zhuǎn)速多少，是指這臺電機每分鐘旋轉(zhuǎn)的周數(shù)，也就是 60秒旋轉(zhuǎn)的周數(shù)。 </p> <p> f:電網(wǎng)頻率，我國為50HZ。 </p> <p> p：電機極對數(shù)，2極電機，湖北中型電機報價，對數(shù)是1；4極電機，湖北中型電機報價，對數(shù)是2；8極電機，對數(shù)是4。比如一臺2極電機，轉(zhuǎn)速n=60秒 </p> <p> ×50HZ/極對數(shù)1=3000轉(zhuǎn)。但這是同步轉(zhuǎn)速，異步電機，轉(zhuǎn)子轉(zhuǎn)速低于定子旋轉(zhuǎn)磁場轉(zhuǎn)速，所以，異步轉(zhuǎn)速還涉 </p> <p> 及到電機轉(zhuǎn)差率的因素，轉(zhuǎn)差率=（定子轉(zhuǎn)速-轉(zhuǎn)子轉(zhuǎn)速）/定子轉(zhuǎn)速，不同廠家生產(chǎn)的電機轉(zhuǎn)差率也不同，通常在 </p> <p> 10％以內(nèi)，一般在4％左右。 </p> <p> 異步轉(zhuǎn)速和轉(zhuǎn)差率關(guān)系：N=(60F/P)×(1-S%)，所以2極電機異步轉(zhuǎn)速=3000×（1-4%）=2880轉(zhuǎn)左右。 </p> <p> 同樣算法，6極電機異步轉(zhuǎn)速=（60秒×50赫茲/極對數(shù)3）×（1-轉(zhuǎn)差率4%）=960轉(zhuǎn)左右。聯(lián)創(chuàng)電機過硬的產(chǎn)品質(zhì)量、質(zhì)量的售后服務(wù)、認真嚴格的企業(yè)管理，贏得客戶的信譽。湖北中型電機報價</p> <span
